Review-Wetting Phenomena in Catalyst Layers of PEM Fuel Cells: Novel Approaches for Modeling and Materials Research

W. Olbrich et al.

Summary: The development of high performance polymer electrolyte fuel cells relies on modeling to optimize cathode catalyst layers, yet there has been a gap in theoretical understanding of wetting properties. This article introduces a novel conceptual approach to address this gap, highlighting the significant impact of ionomer interaction with the Pt/C surface on wetting behavior.

Revealing the Nanostructure of Mesoporous Fuel Cell Catalyst Supports for Durable, High-Power Performance

Matthew Ko et al.

Summary: The study investigates the role of nanoscale morphology in the performance of PtCo catalysts supported on different types of porous carbons. Accessible porous carbons have larger and more numerous mesopores compared to conventional porous carbons, leading to improved local oxygen transport through microporous channels. Although accessible porous carbons show faster rates of electrochemical surface area loss in durability testing, they maintain superior high current density performance at the end of the test due to enhanced local oxygen transport.

Ultralow platinum loading proton exchange membrane fuel cells: Performance losses and solutions

Dustin Banham et al.

Summary: The fuel cell community has made a concerted effort to develop high activity oxygen reduction reaction (ORR) catalysts in order to reduce platinum group metal (PGM) content in proton exchange membrane fuel cells (PEMFCs). However, beyond just ORR mass activity, challenges include kinetic limitations in the hydrogen oxidation reaction (HOR) at the anode and transport limitations related to ionomer/catalyst interactions at the cathode. The critical role of the carbon support in these interactions has been revealed, emphasizing the importance of rational carbon structure design.
